immvron A TTORNEYS For different weaves, different sets of co ns are used. For instance, if it is: intended to weave a six harness twill weave with a four harness twill weave, it is necessary to use six cams and four cams on two different shafts in order to rotate each com. in the corresponding time for producing the desired weave. If it-is desired to make only one twill weave in a piece of cloth, it is only necessary to use one set of cams and one gear wheel and one shaft.

As illustrated in Fig. 2, the three sets of come 19, 20 and. 21 produce three difi'erent weaves in one piece of. cloth and are also capable of producing a three harness twill stripe, a four harness twill stripe and a five harness twill stripe in the some piece of cloth. 1

By driving the sets of cams 19, 20 and .21 simultaneously at each revolution of the shaft 31, the cams 19 are given one-third revolution, the earns 20 one-fourth revolution, and the earns 21 one-fifth revolution, so that each set of cams moves its harness into correct position on every turn of the shafts 31 and 35.

' lit is understood that the cam grooves in the different cams 19, 20 and 21 ere shaped corresponding to the work required. Thus, for instance, the cam shown in Fig. 5 is for a four harness twill. weave, one up and three down. "The cam groove 44 of this coin hes two concentric portions 45 and 46, the ends of which are connected with each other by com portions 47 and 48 to import the tie-- sired rocking motion. to the harness jocks 10, 11 and 12. By the arrangement de scribed each harness remains at e standstill during the time the friction roller es travels in the concentric cam portion es and is raised and lowered during the time trio tion roller 43 travels in the connecting portions 47 oxides. The case shown in Fig. ti is for a tour harness twill weave, two up and two down; the cam shown in Fig. 3" is for a two harness twill weave, one up and one down; and the coin shown in 8 is a twelve harness twill weave, seven up, one down; one up, one down; one up and one down. It is understood that each set of cams has difi'erent time cam grooves to sotuste the jacks intermittently according to the divisions of the time grooves as above described.

The connectors 16, 17 and 18 are alike in construction and hence it suffices to describe but one in detail. One end of each connec' tor 16, 17 and 18 is in the form of an open eye 40 engaging a stud 4.1 on the upright member of the corresponding harness jock 10, 11 or 12. On the other end of each connector 16, 17 and 18 is journoled, by the use of a ball bearing 42, a, friction roller es en gaging a cam groove 44 formed in one face of the corresponding cam 19, 20 or 21.

As shown in l ig, 3, each 17 and 18 extends above the responding com 19, 20 a1 51 and with outer end is providr-zd, wf e. rctm'n hoot arm at? ext (ling under the hub of the cor respondin can i9, 20 or so as to prevent an up or down swinging niovennmt of the connector and. to czmse the com to push and pull the connector alternately in oppo" directions wh. n the loom. is running in V16 oi the bearing which each conic." mu has upon the ngiper end lower fees of its respective coin hub. By the nz'rcngcmc movement is given seine-to prevent the formation of imported; we we. lit will also be noticed that the loom can be run at it high rate of speed owing to the not that the corn and c =nnector lnecliz .iisms for the harness jocks can be run st any speed without danger of improper functioning. The lefbhsnd portion of the shaft 53 4; jonrnsled in suitable nee lg 50 arranged on the main. 1 nine 15-, e. the rightelmnd end at Lee sh: 22 is got; nulcd in a shaft it jonrnelcd in :1 bearing 51. arranged on main frame 15. On the shaft 60 are keyed. or otherwise secured the non motion earns 61 on on the outer 6'3 is secured 2L gear wheel 62 111 mesh with :1, pinion secured on the driving shaft 31 so that the box motion earns 61 rot, zed when the icons is running. The box IHQLLOH. earns (31 are connected in the usnnl nninner with the boxes containing the shuttles for carrying the weft tlniemls through the open.
